Can hunger cause high blood pressure?

While hunger won’t elevate your blood pressure in normal circumstances, starvation can certainly raise your blood pressure. Starvation is a type of malnutrition, which is caused by being deprived of food or eating food that is inadequate for your body’s nutritional needs. Not eating for a day or longer will cause starvation. Starvation and malnutrition have long-term effects on blood pressure, including causing your blood pressure to elevate.

High blood pressure, or hypertension, is a condition where your blood pressure is elevated to a level sufficient to cause you harm. The minimum blood pressure for hypertension to be diagnosed is 140/90 mmHg.
